## Indications for use
The Varian ProtonVision device is used to plan proton radiation therapy treatments employing proton accelerators with energies from 70 to 235 MeV. ProtonVision will plan the 3D radiotherapy proton treatment approaches to rectangle and circular fields, and regular and irregular fields using customized blocking and compensators. ProtonVision includes also tools for treatment preparation (diagnostic image analysis, contouring & segmentation) and plan review. As part of the Varian Vision System, ProtonVision integrates proton treatment planning in overall therapy process, while taking advantage of the Varian Vision database.
